A deadly gas pipe explosion in San Bruno, California last week left at least four people dead and nearly 40 houses destroyed. The company being held responsible is Pacific Gas & Electric, better known as PG&E. It could be more than a year before investigators determine precisely what caused the explosion. For years, however, California residents have accused PG&E of irresponsible safety practices.

We talk with David Baker, energy reporter with the San Francisco Chronicle, who's been covering PG&E for the past six years.
